[This is probably a YaBB problem, but I'm posting it here because email to firstname.lastname@example.org bounced back: "mailbox is full: retry timeout exceeded"]
I got an internal server error (see below) trying to do a search in the forum using Mac OSX 10.5.8 with Safari 4.0.2.
I have done a reasonable amount of testing to try to track this down, and it seems that it occurs when the "Message" box is checked as well as the "Subject" in the "Fields to Search" setting. Sometimes if I reduce the search to less than "(all posts)" or "year" it will succeed, so perhaps it has to do with the volume of searching?
